My wife slowly rocking her body on another man's

I heard them as soon as I opened the front door, but I couldn't believe it! But when I moved the curtain a few inches, there, mere inches from me, was my wife, slowly rocking her body on another man's!

Upon seeing proof of my wife's infidelity, deep despair in my heart, but then shockingly, it was slowly replaced by an unexpected feeling: lust!
